Specification of Letters Patent. Patented Apl". 10, 1917.

Application filed September 26,1914. Serial No. 863,739,

To all whom) it may concern} Be i known that I, J GRovE BROWN, a

citizen of the United States, residing'Qat. Groton, in the county of Tompkins and State of New York, have invented certain new and useful Improvements in Dumping- Wagons, of which the following is aspecification.

The purpose' of this invention is to provide convenient means, for tilting the bodies of endwise dumping vehicles and for holding the bodies in any desired positions of adjustment. The invention is particularly 1 ,usefulalso upon vehicles for other purposes.

desirablein; connection with chute wagons used for distributing broken stone in layers upon'roadways, as illustrated, for instance,

in 'm'y copending applications, Serial No. 796,436, and, Serial No. 862,957, although In chute wagons for the purpose stated, the material is transported to the .point where the stone is to be laid, the bodyis then tilted rearwardly and the vehicle is moved forwardly while the material flows out through the chutes, and islaid in an even layer upon.

the roadway. As the vehicle carries usually a heavyload of stone, the center of mass of which shifts'when the body is tilted, and as the angle'to which the body must be tilted with respect to the frame, to cause the stone to flow, varies according to th grade. of the roadway, it is necessary to provide safe and convenient means by which the operator can control the tilting movements of the body and lold the body in any position of adjustinent.

These objects are attained by the present improvements, the details and operation of which wi l beclear from the following specification taken in connection with the ac'companying drawing, in which,

Figure 1 is a side elevation of part. of an vendwise dumping vehicle, having my improvements applied thereto, the body being shown in normal position in'full linesand in dumping'position in dotted lines;

Fig. 2 is a detail View showing the brake .\-for the Windlass;

Fig. 3 is a front elevation of the hoisting and lowering mechanism and the locking and braking devices; and, Fig. 4: is a detail view of one end of the upright to -vhich the hoisting and lowering chains are attached.

Referring to thedrawing, A indicates an endwise dumping vehicle, comprising a body ing between the standards.

1 pivotally mounted at 2 in bearings supported from the vehicle frame 3. Upon the forward portion of the'vehicle frame, at the rear of the drivers seat 4, are secured a pair of standards 5, and in front of these'are braces 6 extending from the standards down to the foot platform 7. A shaft '8 is mounted' in suitable bearings in the upper ends of the standards 5, and upon this shaft is a winding drum 9 A gear 10 upon the shaft of the winding drum meshes with a pinion 11 on a short shaft 12'supported by one of the standards 5 and by a short standard 5, the latter secured to cross-pieces 13 extend- 14, .upon the shaft 12, is provided for the purpose of operating the gears to turn the winding drum 9 in either direction. Two chains or cables, 15 and 16, are attached to the drum near its opposite ends and arranged to wind and unwind oppositely thereon; that is, when the drum is turned, one chain will wind on to the drum while the 'other chain will unwind. One of these chains, 15, has its free end connected to the upper end of abowed upright 17 which is secured to the front endboard 18 of the wagon body and projects above and below the same, and the other chain, 16, has its vfree end connected to the lower end of the upright 17 It will be evident that by turning the crank 14 in one direction, the chain 16 will pu l upward on the upright 17 and .raise the orward end of the wagon body,

while the chain 15, at the same time, will pay ofi or unwind from the drum 9. and Will steady the upward movement of'the body and prevent it from being tilted by the load it will also be evident that when. the hand crank is turned in the opposite direction, 'the chain 15 will wind on to the drum and pull the forward end of the body downward,

A hand crank' ing in the opposite end 20 of the band. This V spring is interposed between the latter end of the band and a bell crank lever 23 pivotally mounted-on the band, the arrangement being such that the spring normally presses the band firmly against the brake wheel to prevent rotation of the drum of the windlass. The bell crank lever 23 has one arm connected by a rod 24 to a lever 25 which is secured to a shaft 26 mounted in bearings 27 'on the-standards 5, and this lever is connected by a rod 2% to afoot lever 28 suitably pivoted adjacent the footboard 7 in such'position that the .driver may'readily place his foot upon-the lever and thereby cause the spring pressed brake band to be released from the brake drum. A lever 29 is also attached to the-shaft 26, anda locking bolt 30 is pivotally connected to this latter lever.

The lockingbolt or latch bolt is adapted to engage-a recess 31 in a plate'or block 32, on the front of the wagon body, and a spring 33, surrounding the bolt, normally presses v, the latter to its locked position.

When the w'agonb'ody is in its normal position, the locking bolt engages the recess 31 and locks the wagon body against tilting movement. For transporting material the .wagon' body will remain'normally locked.

erator lifts his foot from the foot lever and the spring pressed brake band then grips the brake drum and prevents further turning of the drum and'tilting of the body. If itis desired at any time while the load is beingdelivered on the roadway, to change the angle of the body, the operator releases the brake by pressing upon the foot pedal and then turns the Windlass as much as is necessary to bring the body to the proper angle.

The foot controlled brake is alsoa desirable feature in regulating the movement of the wagon body when the load therein tends to Jopies of this patent may be obtained for race the windlass, as it enables the operator to check or stop this racing. In bringing the body back from the tilted to the horizontal position, the operator holds the foot lever down until the body reaches the horizontal position, varying the pressure more or less if a braking action is desired, and when the bodyreaches the horizontal position the foot lever is released and the body thereby becomes locked and. the brake becomes set on the windlass.

The upright 17 is made in two parts, as shown, bowed. oppositely for the sake of strengthening it laterally, and the chains are connected to threaded eye bolts 17 (Fig. l), mounted in cross-pieces 17" between .the arms of the upright. By means of these threaded eye bolts, the slack in the chains may be taken up and adjustments made to compensate for wear. The upright 17 is arranged so that its ends swing in a plane centrally of the winding drum, and as this upright is made comparatively long, and the chains are arranged to wind toward the center of the drum, the angle at which the chains pull upon the upright is'very slight in any position of the wagon body, and this arrangement obviously lessens the labor of operat ing the windlassand avoids straining the parts. What I claim is: In an endwise dumping vehicle, a frame,

thereof, an endwise tilting body, an upright secured to the front of the body, oppositely winding chains or cables 'on the Windlass connected, respectively, to upper and lower parts of the upright, a lock for locking the body, in its lowered position, to the frame,

.a windlass supporteduponthe front end' a brake forthe Windlass, a manually operable lever, and connections between said lever and said lock and brake for releasing the lock and brake.

In testimony whereof I have afiixed my signature, in presence of two witnesses.
